I'm also there and not very active. Recently I was annoyed by some high-rank members via PM after I was speculating about spammers on that forum. Quite surprised that many spammers are able to do 100 posts/day even some of them are done by their moderators. I said they're probably bots and they didn't accept it, LOL.
Yes I have a high rank here too. On Altcoinstalk you cannot spam continuously because its system only allows continuous post after 90 seconds, and it checks by IP. I don't know how they can spam like you said.
